selftests: drv-net-hw: add test for memory allocation failures with page pool
Bugs in memory allocation failure paths are quite common.
Add a test exercising those paths based on qstat and page pool
failure hook.
Running on bnxt:
# ./drivers/net/hw/pp_alloc_fail.py
KTAP version 1
1..1
# ethtool -G change retval: success
ok 1 pp_alloc_fail.test_pp_alloc
# Totals: pass:1 fail:0 xfail:0 xpass:0 skip:0 error:0
I initially wrote this test to validate commit be43b7489a3c ("net/mlx5e:
RX, Fix page_pool allocation failure recovery for striding rq") but mlx5
still doesn't have qstat. So I run it on bnxt, and while bnxt survives
I found the problem fixed in commit 730117730709 ("eth: bnxt: fix counting
packets discarded due to OOM and netpoll").
